1951 Germany 2 DM (Pattern) Blank Planchet

Both sides are blank (Type 2 planchet), with lettered rim (& oak leaves). Coin is weakly magnetic (CuNi), 6.91 g, 26.58 mm by 1.9 mm

For now, I have placed this one in the “pattern” category (i.e., on a Max Planck planchet).

 But … what did you want to know?  

Just a title and details and pictures - but no question, in the forum > 

Coin identifications and valuations 

😐 

Well, how about, “Does that sound right to you?” &/or “Does anyone else have any details on German blanks?”

I'm always interested in more information.

Cheers

Hi,GregbythePond! No,you misplaced your coin in the pattern category! Almost all such blank planchet coins(with one side or both sides of the coin being blank) are clasified as minting ERRORS. Generally,these kind of errors(as others too!) are very rare & valuable for those who collect error coins. This sort of error(which is a misleading of the minting process)is (and may be) found on every country's coinage,not only on some german coins. There are already known blank planchets for U.S.dollars and a lot of other countries' different coins. Of course,all these coins have correctly minted edges(lettered,with simbols or reeded).

I found the above information on the internet,by searching with Google the topic ''blank planchet german coins''. Simple,isn't it?!

P.S.: In some cases,such error coins may have also a not minted edge,the only identification remaining data being the kind of metal,weight & diameter(as to outstand it as a ''coin'',compared to a simple round piece of metal).

To me it looks more like a manipulated coin, be it machined or otherwise altered.

Also the most CuNi alloys used in coins have too little nickel to be magnetic. Since 1969 the 2 mark coins were made with Magnimat which had a nickel core which is magnetic. 

Yes,Idolenz,''since 1969…'' but,please note,the submited coin is said to be a 2 mark from 1951. 

He just said he put it under Max Planck, it obviously is not a planchet used for that coin or at least not intended, also how should a specific date be derived from an empty field?

I think,colleague Idolenz,that the poster of the topic determined the year by the type of lettered edge + weight,diameter,metal(as I myself said in my post-reply).🤔

The KM111 and km116 (1951D-1971J) were all made of just Cu-Ni and thus not attracted to a magnet

The KM124, KM149, KM170, KM175, KM183 and KMA127 were all made with a Ni core and clad with Cu-Ni and are slightly attracted to magnet. Those KM# span the period from 1969 to 1987. This Idolenz already pointed out.

So the shown coin can NOT be a Planck, KM116.

The next step would be to compare the oak leaves, to see if any of the possible KM# have the same ones to those shown by the OP (to try to find the possible date range on the OP's coin. I'll leave that up to him.

In numista we don't have a very precise description of the edges of the different KM#, except the inscription by itself :

EINIGKEIT UND RECHT UND FREIHEIT

I've made images of the edges of the 6 possible coins:

km124

km149

km170

km175

km183

kmA127

Si if somebody wants to try to figure the year of yearless coin, the basis is there.

Those pictures are fantastic!  Please tell us how you create them showing the edge in 360°.

One steeples night in 2013 I figured out the principles and then it was easy!

An example on a Dutch coin

Very simple, not costly. I have documented it in numista before, But I don't know where… Anyway, I don't use GIMP2 anymore, since I don't really find any need to isolate the edge.

I also used it once in a documentation of Swiss 5 frank coins, just for my own fun

N#194 has some similar documentation in the comments section, I think, that's the reason I didn't infuse those in numista!

Enjoy your reflector shopping, it's worth it.

https://en.numista.com/forum/topic113104.html the principle not really understood, I would say?

We miss somewhere in numista tu put themes like edge photos and how to show off-sets

Fantastic!  Thanks.  Too bad Numisdoc is dead. This would be the perfect place:  https://en.numista.com/numisdoc/pictures-and-images-on-numista-141.html 

First attempt.  Straight forward and relatively easy.

Weren't you lucky to have the year and mint mark under the President's chin😉

I suppose, your found the reflector in an old, no longer used pocket lamp in the garage?

Happy Holidays and a Healthy New Year.

Actually found one in the basement.

Happy New Year to you, too.

One has to buy them now, since the led-lamps will NOT give you this kind of reflector (I think).

How can one insert anything there?

Well, this would be a pattern coin with an error (two blank sides) and edge lettering only. PS “google it” is not terribly useful.

Also the most CuNi alloys used in coins have too little nickel to be magnetic. Since 1969 the 2 mark coins were made with Magnimat which had a nickel core which is magnetic. 

Well, there is this; “Only a few pieces of this coinage are known. It is a 1 DM coin with an extremely rare magnetic alloy variant, issued in 1950.” So magnetic variants do appear to exist, as early as 1950.

From Greg to me:

However, “Only a few pieces of this coinage are known. It is a 1 DM coin with an extremely rare magnetic alloy variant, issued in 1950.” So my reasoning goes that a 1951 2 DM magnetic (weakly) coin is not necessarily unlikely.

My comments on “Max Planck” are based on those from the pattern (N# 307865) listing, as follows; 

"Edge Plain with inscription.

Lettering: EINIGKEIT UND RECHT UND FREIHEIT

Translation: Unity and Justice and Freedom

Mint

D

Munich, Germany (1158-date)

Comments

Minted on Max Planck planchet"

So my mystery remains… the physical evidence matches that of the 2 DM “pattern” listing N# 307865.

I'll observe that the edge descriptions are notoriously imperfect.

Do you have an edge photo of the 1951 2 DM? I'd like to see if the edge matches….

Here the images:

1951D

1951F

1951G

1951J

Use the as you like, maybe concentrate on the oak leave separators?

All the best for 2023

Thanks for those! Hard to identify based on oak leaf separators alone. More research required. 🤔

At least you have the material you asked for. Have some happy research hours😁
